SCOTT, OF CHICKASHA, OKLAHOMA, ASSIGNOR, BY MESNE ASSIGNMENTS, TO SCOTT PATENTS CORPORATION, OF CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS METHOD AND DEVICE FOR INSERTING PADDING' INTO UPHOLSTERY Application led June 7,

This invention relates to a method and a device for inserting padding into piping` for forming cushions or upholstery.

An object of the invention is the provision of a device for distending a plurality of pipings and for forcing and packing the padding into the piping through an alternate reciprocation of a plurality of toothed plates.

Another object of the invention is the provision of a method of packing padding into a plurality of connected pipings by distending the piping in line with a confined space through which the padding is fed, while advancing the padding at diametrically opposite points, and in an alternate relation.

A further obj ect of the invention is the provision of a device for inserting and packing pa lding strips into piping` in which a plurality of plates are operated in pairs with one plate being moved in one direction, while a coordinate plate of a pair is movedv in the opposite direction, said plates being located on opposite sides respectively of the padding strip, teeth being-provided on the plates and having their free ends extending` towards the direction of movement of the plates for engaging and forcing the padding forwardly into the piping, while being released from the padding upon the return stroke so that at all times some part of the padding is being moved into packed relation in the piping and being fed in a continuous stream to the reciprocating plates.

This invention will be best understoodfrom a consideration of the following detailed description in connection with the accompanying drawings; nevertheless, it is to be understood that the invention is not confined to the disclosure being susceptible of such changes and modifications as shall define nomaterial departure from the salient features of the invention as expressed in the appendedclaims.

In the drawings Figure 1 is a plan view of a device for inserting padding into piping and constructed according to the principles of my invention,

Figure 2 is one side view of the same, Figure 3 is an opposite side view of the device, Y

1928. Serial No. 283,659.

Figure 4 is a longitudinal section of the padding inserting device,

Figure 5 is a transverse vertical section taken along the line of Fig. 4.

Figure 6 is a transverse vertical section taken on the line 6-6 of Fig. 4.

Referring more particularly to the drawings 10 and 11 designate legs of angle iron construction for supporting a frame work of the device for inserting padding into pipings. Side plates 12 and 13 are supported by the legs and connected together by transverse members 14, l5 and 16.

A plurality of tubes 20 for receiving the piping which is adapted to be filled with the padding, are located in a horizontal plane and are supported by the spaced parallel transverse plates 14. These tubes extend longitudinally of the frame and project outwardly from the discharge end of the device. The tubes terminate at 21 with their inner ends adjacent the inner ends of the feeding tubes 22. The tubes 22 are located in alinement with the tubes 20. It will be noted that the feeding tubes are of smaller cross sectional area than the tubes 2O and aie located between pairs of slidably mounted feeding bars 23 and 24. Spacing bars 25 are located between each pair of feeding tubes 22.

The reciprocating plates 23 and 24 are engaged upon opposite sides of the feeding tubes 22. These plates have teeth extending from their adjacent faces in a direction which is toward the outer end of the tubes 2O so that when the plates are moved forwardly the teeth will engage the padding and force the same outwardly, while the teeth are released during the return stroke of the plates. The outer ends of these plates are supported in spaced relation by the padding which is being forced into the piping from the open ends 31 of the tubes 20.

Each of the plates 23 is provided with a pair of spaced ears 32 having vertical slots 33 to receive pins 34 carried by the lower end of an oscillating arm 35. The arms 35 are `pivotally mounted on a rod 36 extending between the opposite sides of the machine and supported in brackets 37 secured to the side plates 12 and 13. A rod 38 extends through several oscillating arms 35 for connecting said arms together for simultaneous oscillating movement. A pair of pitmen 40 are pivotally connected at one end to the rod 38 and at the other end are pivoted on a rod 42 extending between a pair of crank arms 41, which latter are fast on a pair of alined stub shafts 43 j ournaled in the side walls 12 and 13.

A similar mechanism is employed for reciprocating the lower plate 24, the same consisting of ears 55 attached tothe under side of each plate and formed with vertical slots 54 to receive a pin 53 in the upper end of an arm 45 pivoted on al transverse rod 46 mounted in brackets 47 attached to the side plates 12 and 13. Through the several arms 45 eX- tends a rod 48 to which is connected one end of a pair of pitmen 49, said pitinen being pivoted at the other end on a transverse rod 50 mounted in and between a pair of crank arms 51 that are fast on stub shafts 52 journaled in the side plates 12 and 13.

Referring more particularly to Figs. 2 and 3 it will be seen that a system of sprockets and chains is employed for rotating the shafts 43 and 52 from a drive shaft 60. On one side of the device a sprocket chain G1 is trained over sprocket wheels 62 and 63 on the' shafts 43 and 52 respectively and yover a driving sprocket 64 on the drive shaft 60, the chain being maintained taut by an idler sprocket 65. On the other side a similar chain 61nu is trained over sprockets 62a and 63a on the shafts 43 and 52 respectively and over a drive sprocket 64 on the drive shaft 60, being kept taut by an idler sprocket 65a.

An upper peripherally toothed feed roll 71 is formed with end pintles journaled in the side plates 12 and 13 and is driven from one of the shafts 43 by a sprocket wheel 74 fast on shaft 43, a sprocket chain 78a, and a sprocket wheel 72 fast on one of the feed roll pintles 70. The lower peripherally toothed feed roll 75 is formed with end pintles 76 journaled in the frame plates 12 and 13 and is drivenfrom one of the shafts 52 by a sprocket 79 fast on shaft 52, a sprocket chain 78, and a sprocket Wheel 77 fast on'pintle 76, the chain 78 being trained over an idler sprocket 8O journaled on an extension of the frame plate 12. It will be noted by reference to F ig. 4 that the feed rolls 71 and 75 are located in spaced relation adjacent to the outer end of the feeding tubes 22, the space between said rolls being substantially in line with the axes of said tubes. In front of the feed rolls 71 and 75 are mounted two series of alternating feed chutes 83 and 84, for the padding; the upper series 83 being downwardly inclined toward the feed rolls and the lower series 84 upwardly .inclined toward the feed rolls. Lips 85 and 86 are provided at the outer ends of the chutes 83 and 84 forproperly directing the padding into said chutes. By reason of the V-shaped form of the chutes, converging toward the feed rolls, the outer wide ends receive the padding, and the latter is gradually compressed or reduced in width, and correspondingly increased in thickness, as it reaches and is forced by the rolls into the feeding tubes 22.

The operation of my device is as follows: A piping is formed of some suitable fabric and is arranged in parallel series and slipped over the horizontally disposed tubes 20, shown in Fig. 2. The padding is placed in the guides 83 and 84, and the free ends are inserted between the rolls 71 and 75. Power is applied through the shaft 60 and the chains and sprocketsy cause oscillation of the arms 35 and 45 and likewise the reciprocating plates 23 and 24. The padding having been reduced in cross sectional area by the inner ends of the guides 83 and 84 is fed by the rolls 71 and 75 into the .feeding tubes 22. After the padding projects from the inner end of the tubes 22, it is engaged by the teeth 30 of the reciprocating plates 23 and 24 which move the padding along, and pack it against the closed end 101 of the piping 100. As th-e padding is packed and forced against the closed end, the filled piping is progressively moved from the tubes while being lilled. It will be noted that the plates 23 and 24 move in opposite directions in alternating relation so that while the plate 23 is moving outwardly, the plate 24 is being returned. By this means the padding is moved forwardly along its upper edge by the plate 23 after which it is moved along its lower edgeby the plate 24. It will be seen by this construction that the operation of inserting the padding into the piping is not only continuous, but an even distribution of the padding is had by the alternate reciprocations of the plates 23 and 24.
